  • Patent number: 7390533
    Abstract: The automated system includes a fluid dispenser having an applicator tip which is used to apply a fluid to an object. A compliance mechanism is utilized to assist in maintaining the applicator tip of the fluid dispenser in contact with the object during the coating operation. A robot can be utilized to advance the object past the applicator tip during the coating operation. The fluid dispenser is mounted on a movable arm to allow the fluid dispenser to be moved or rotated into and away from the position where fluid is applied to the object. The automated system provides a fluid application system that can apply a precise and repeatable layer of fluid to an object. The use of the robot allows larger objects to be easily handled and for the coating process to be done in a rapid fashion. The automated system is flexible and can readily accommodate changes in the object that is to be coated or the configuration of the coating that is to be applied to the object.

  • Patent number: 5743959
    Abstract: A reusable applicator tip for applying a uniform band of liquid material, such as an adhesive compound, along a selected portion of the peripheral margin of sheet material. The apparatus includes a pad block designed for receiving and transmitting liquid material onto a transfer pad for application onto the sheet material. The liquid flows through internal channels in the pad block and onto an exposed portion of the transfer pad for application onto the sheet material. The transfer pad is removed and replaced at the end of its useful life permitting continued use of the pad block. The apparatus also includes a removable edge guide which permits the selective replacement of the edge guide for varying sheets of material. Excessively worn edge guides may also be replaced without disposing of the entire pad block.

  • Patent number: 5131349
    Abstract: A system for applying a uniform band of liquid primer material to the marginal edge surfaces of glazing units upon which a plastic frame or gasket member is to be molded in place. A family of interchangeable applicator tips is provided for use with a dispensing device adapted to provide an on-demand supply of primer material to the tip in use. The different applicator tips of the family have configurations particularly adapted to applying bands of primer material along selected peripheral margins of a sheet member. Each is of a composite construction including a relatively rigid base member covered by a soft absorbent body for contacting and transferring to the sheet surface the layer of primer material. The tips are readily attachable to and removable from the primer material dispensing device.

  • Patent number: 4457340
    Abstract: A power-assisted valve is provided which is particularly effective for systems handling viscous materials, such as certain metering systems. The check valve operates effectively even with highly-filled viscous resins used in such systems. The valve includes a valve seat and a valve ball which can be urged toward the valve seat to a closed position by a fluid-powered cylinder and piston. The piston rod is separate from the valve ball so that the ball can rotate relative to the valve seat.

  • Patent number: 4273261
    Abstract: Apparatus for metering material and transferring it from one location is provided. The new metering apparatus has several advantages over that disclosed in my U.S. Pat. No. 4,118,799. The apparatus includes a pair of cylinders with rams which are reciprocated in opposite directions by gear racks connected thereto and driven by a common pinion. A plurality of pairs of the cylinders and rams can be mounted on a common frame or base to meter a number of different materials. Also, the rams, with or without the cylinders, can be readily replaced with components of different diameters to provide different metered quantities of materials. In addition, mechanism are provided for changing the stroke lengths of one or more pair of rams when two or more pairs are employed.

  • Patent number: 4266383
    Abstract: A resilient sealing member for use about the marginal edge of a glazing panel mounted in a solar energy collector. The sealing member is cup-shaped for receiving the marginal edge portion of the panel and is formed with a sealing lip bearing against the outboard surface of the glazing panel to provide a fluid tight, pressure seal adjacent the entire periphery thereof. The sealing member is advantageously used in combination with a retainer assembly having a retainer cap that exerts pressure on the sealing member to urge the lip into uniform, pressure sealing contact with such outboard surface.
